yeah, that's called a tank slapper and they SUCK. glad to hear you came out of that one okay. even with the top racers, they get launched when this happens to them. the scariest one i've seen someone get out of was Tommy Hayden at mid-ohio (i think) at race speed.......big frggin props to him for riding that out and immediately nailing the throttle like it hadn't even happened. NEVER rip one up with the bike sideways.
